| Title of Invention | MITIGATION OF MEMBRANE DEGRADATION BY MULTILAYER ELECTRODE |
|---|---|
| Abstract | An MEA for a fuel cell that employs multiple catalyst layers to reduce the hydrogen and/or oxygen partia pressure at the membrane so as to reduce the fluoride release rate from the membrane and reduce membrane degradation. An anode side multi-layer catalyst configuration is positioned at the anode side of the MEA membrane. The anode side multi-layer catalyst configuration includes an anode side under layer positioned against the membrane and including a catalyst, an anode side middle layer positioned against the anode side under layer and not including a catalyst and an anode side catalyst layer positioned against the anode side middle layer and opposite to the anode side under layer and including a catalyst, where he amount of catalyst in the anode side catalyst layer is greater than the amount of catalyst in the anode side under layer. |
